FakeMonowavePlatform class

An in-memory MonowavePlatform.

This fake records each request and answers with canned values. As a result, a test asserts on the request and not on bytes that the test must decode.

Constructors

FakeMonowavePlatform({int abi = 1})

Properties

abi ↔ int

What abiVersion reports.

getter/setter pair

bytePlaybacks → List<(int, WaveformDocument)>

Every byte-playback requested, as (byteLength, document).

final

byteRenders → List<(int, WaveformDocument)>

Every byte-render requested, as (byteLength, document).

final

decoded → Map<Object, WaveformPeaks>

The peaks that the decode methods return, keyed by path or by byte length. An input that is not in this map gets defaultPeaks.

final

decodeRequests → List<Object>

Every path passed to decodeFile, and every byte length passed to decodeBytes, in order.

final

defaultPeaks ↔ WaveformPeaks Function()

If the input is not in decoded, the decode returns this value. The default is two seconds of silence at 44.1 kHz.

getter/setter pair

exports → List<(String, String, WaveformDocument)>

Every export requested, as (sourcePath, outputPath, document).

final

hashCode → int

The hash code for this object.

no setter, inherited

initializeCount ↔ int

How many times a caller awaited ensureInitialized. This count shows a host that loads the C core on every build instead of one time only.

getter/setter pair

nextCaptureError ↔ Object?

If a test sets this field, openCapture throws it and opens no session.

getter/setter pair

nextDecodeError ↔ Object?

If a test sets this field, the next decode of either kind throws it.

getter/setter pair

nextExportError ↔ Object?

If a test sets this field, the next export throws it.

getter/setter pair

nextPlaybackError ↔ Object?

If a test sets this field, openPlayback throws it and opens no session.

getter/setter pair

nextRender ↔ Int16List?

What renderPcm returns. The default is silence with one frame for each source frame that the document describes. As a result, a host can assert on the length with no need to synthesize audio.

getter/setter pair

nextRenderError ↔ Object?

If a test sets this field, the next render throws it.

getter/setter pair

nextResult ↔ MinMax?

If a test sets this field, reduceMinMax returns it and does not reduce the samples.

getter/setter pair

playbacks → List<FakePlaybackSession>

The sessions that openPlayback returns, newest last.

final

reductions → List<Int16List>

Every window passed to reduceMinMax, in order.

final

renders → List<(String, WaveformDocument)>

Every render requested, as (sourcePath, document).

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sessions → List<FakeCaptureSession>

The sessions that openCapture returns, newest last.

final

Methods

abiVersion() → int

The ABI version of the C core. Each time a signature in src/ changes, this version increases.

override

decodeBytes(Uint8List bytes, {int baseSamplesPerPixel = 128}) → Future<WaveformPeaks>

This method decodes a container that is already in memory. On web, this method is the only decode path.

override

decodeFile(String path, {int baseSamplesPerPixel = 128}) → Future<WaveformPeaks>

This method decodes the audio file at path into a peak pyramid.

override

ensureInitialized() → Future<void>

If the C core is not loaded already, this method loads it. A second call does nothing.

override

exportWav({required String sourcePath, required String outputPath, required WaveformDocument document}) → Future<void>

This method reads from sourcePath and writes document to outputPath as 16-bit PCM WAV.

override

install() → void

Installs this fake as the platform. Call uninstall in tearDown.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

openCapture([CaptureConfig config = const CaptureConfig()]) → Future<CaptureSession>

This method opens a microphone capture session.

override

openPlayback({required String sourcePath, required WaveformDocument document}) → Future<PlaybackSession>

This method reads from sourcePath and opens a playback session over document.

override

openPlaybackBytes({required Uint8List bytes, required WaveformDocument document}) → Future<PlaybackSession>

This method opens a playback session over bytes that are already in memory.

override

reduceMinMax(Int16List samples) → MinMax

This method reduces samples to the pair of extremes that the samples span.

override

renderPcm({required String sourcePath, required WaveformDocument document}) → Future<Int16List>

This method renders document to 16-bit PCM and writes no file.

override

renderPcmBytes({required Uint8List bytes, required WaveformDocument document}) → Future<Int16List>

This method renders document to 16-bit PCM from bytes that are already in memory.

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

uninstall() → void
